No, everything boots properly when I ext2.  I should add some more info:
 - When it mounts the jffs2 FS, it does it instantly which means that it
   can't be mounted.  Mounting it properly takes about 20 seconds.
 - In my initrd linuxrc, I can run:
   mount -t jffs2 /dev/mtdblock/1 /
   and it works just fine.  Then the kernel unmouts / and tries to mount
   it again.

I've gotten past the problem by making my /dev/hda1 boot partition a
mini-root with just busybox and it then mounts the JFFS2 partition and
pivot_root's to it.

If anyone has an idea though as to why the kernel can't mount it, I'd
love to skip that kluge.

Thanks,

Dan
